Some vintage earrings (mostly screw back)

Hello, again! Still looking into a jeweler who specializes in vintage jewelry to look at my amethyst necklace. But in the meantime, here are some vintage earrings I’ve come across. Mostly screw back earrings. Just want to show them and maybe get your opinions on them.

I like these two, in particular. I can imagine them being worn by a bride. 50s or 60s, maybe? What do you think?



Found both of these on Etsy some time ago.



I understand this one is most pretty modern, even though I did buy it at an antique store. I still wanted to show it anyway.



This is the one I’m most curious about. Is this supposed to be a shamrock? Or something else entirely? I’ve never seen anything like this before.

 

They look to be mostly costume except perhaps for the amber color pierced (which aren't really vintage) and the bottom pair. Both could be silver. Any marks?

 

The amber ones may well be technically vintage by now, but they're not nearly as old as the rest. The last set look like glass set in silver; I agree that the rest look like vintage costume.

 

Definitely costume. No marks that I can find. The only noticeable thing I can tell is one of the screws may have been replaced at one point.

 

They are definitely glass. One of the glass “stones” is unfortunately chipped.
